I'd wagger because the story works on multiple levels and some characters are quite multidimensional.

Take the main bad guy, Immortan Joe.

On one hand, he gate keeps access to water, he keeps sex slaves and he doesn't blink sending his War Boys to die.

On the other hand, there is nothing in the film pointing to there being a large reservoir of water, yet he does share some with the people around his citadel. He is also portrayed as quite sick and having only two surviving children: a deeply physically flawed one and a dimwit (and they made this one a pedo in the prequel). Maybe all he wanted was a sane and healthy offspring to eventually take over in running the community he built.

There is quite a bit more to talk about, like the war boy's arc, or the lack of gratuitous sexiness, or how Max is not that relevant for the entire story, but I believe this film works so well is because it gives so many opportunities to overthink things and that's always a fun thing to do.
